MAGEINE FOR. TREAT Be it-known that'I, CHARLES P. BossnRr, a citizen ofthe United States, residing at Milwaukee, county of Milwaukee, State ofWisconsin, have invented a new and useful Machine for Treating Hides andSkins, of

which the following is a specification.

My invention relates to a novel construction of a machine for treatinghides and skins and relates more particularly to apparatus for applyinghair removing 'compounds thereto, such as a sulfid compound, which isusually composed of sulfid of soda and lime which is applied to theflesh side ofa skin and is allowed to'remain on the skin or hide .for ashort time so as topermeate through it and has the effect of loosen-.ing the hair, so that it may be readily removed by a subsequentoperation.

This sulfid compound is of a thickplasti'c nature, and by my novelconstruction, sulphi'd solutions of any consistency can be agitated andapplied to any class of leather with absolutely unvarying uniformity,the quantity applied being readily varied to suit requirements and muchbetter results being obtained than by hand labor.

Other important advantages of my invention are the saving of the hair bymy novel machine as considerably less of this is damaged than by hand,labor, and the sulphid is not wasted as any surplusage is pumped backinto the tank.

To the above ends, my invention consists of novel means for agitatingand applying the sulphid compound and of'a novel attachment to themachine of my prior U. S. Patent No. 1,300,920, all as will behereinafter fully set forth and pointed out in the claims.

It further conslsts of a novel construction of sulfid pan or hopper,which is supported ING HIDES LAND SKINS.

7 hopper or pan which receives and delivers the sulfid compound to thefeed roll, whereby said pan and its adjuncts can be readily disconnectedfrom the machine housing and thus rendered readily accessible whendesired. i For the purpose of illustrating my invention, I have shown inthe accompanying drawings forms thereof which are at present practicesatisfactory and reliable results, although it is to be ,understood thatthe various instrumentalities of which my inpreferred by me, since theywill give in Figure 1 represents a perspective, front view of a sulphidpainting machine or a machine for treating hides, skins and the like,embodying my invention.

Figure 5 represents a diagrammatic plan vie-w,.showing the drivingmechanism, certain of the parts being omitted for clearness ofillustration.

.Figure 6 represents, on a reduced scale, a section on line 6-6 ofFigure 3'.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings.

1 designates my novel sulphid machine, thesame comp-rising the framework2, which has mounted in the front thereof the drum 3, and in the rearthereof the drum 4 over which passes the endle$ apron, belt or bolster5, upon which the hides or skins tobe treated are placed, said apronmoving the hides under the mechanism for applying the sulfid compoundthereto, and said drums being supported and rotated by any suitabledriving mechanism, as the driving shaft 6.

7 designates a pinion on said shaft 6 in mesh with the gear 8 mounted onthe shaft 9-which carries the pinion 10 in mesh with the gear 11,mounted on the shaft 12 on which latter the drum 4 is mounted, it beingunderstood that the rotation of the drum 4 actuates the endless belt orapron 5 and the drum 3. power being applied to the shaft- 6 by thepulleys 13. V

14 designates a sprocket wheel mounted on the shaft 9 around whichpasses the sprocket chain 15, whereby the sprocket wheel 16 fast on theshaft 17 is driven. 18 designatesa pinion fast on the shaft 17, and inmesh with the pinion 19, which rotates in unison together with thesprocket wheel 20 on the shaft 21, as will be understood from the top ofFigure 5 and the left of Figure 1.

22 designates a sprocket chain driven by the sprocket wheel 20, wherebythe sprocket wheel 23, mounted on the shaft 24 is driven.

' The shaft 24 carries the feed roller 25 which is rotated at arelatively slow rate of speed and at its end opposite to the sprocketwheel 23 said shaft carries the sprocket wheel26 (see Figure 3) aroundwhich passes the sprocket chain 27, which drives the sprocket ,wheel 28,carried on the shaft 29, which has thereon the roll 30, which isprovided with the agitator or helical surfaces 31 (see Figure- 3) whichare juxtaposed to the feed roll 25. 32 designates the sulfiddistributing means the same comprising the shaft 33 and a plur'ality 'ofradially projecting flexible strips or wiping elements 34, which may beof any desired number, and secured. to the shaft 33 in any desiredmanner, said strips extending across the machine throughout the entirelength of the feed roller 25.

' The shaft 33 and its adjuncts may be rotated from any suitable sourceof power as by a belt applied to the pulley 60 and is preferably rotatedat a considerably greater speed than the feed roller 25, it beingapparent that the parts are so positioned that when the shaft 33 isrotated in the direction of the arrow in Figure 4 the flexible strips 19will contact with the surface of the feed roller 25 removing theadhering sulfid compound therefrom and throwing it down towards theapron or bolster 5. The feed. roller 25, the agitators 31 and the sulfiddistributing means 32 may be enclosed by a suitable guard or casing 35,and while the sulfid pan or hopper 36 may be variously arranged andsupported, I preferably construct the same of the end members 37, andthe bottom or body member 38, having the end brackets or arms 39,terminating in the upright end flanges 40, which are b lted or otherwisesecured to the flanges 41 of the housing 42, which carries the bearingsfor the feed roll 25 and the distributing means 32 both ends of the panor ho per 36 being substantially the same,

' as Wil be understood from Figures 1, 3

and 4.

The sulfid compound is pumped from the lower receptacle 43, see Figure2, by means of the pump 44 and the pipe 45 into the tank 46, which issupported above the machine in any suitable manner. said tankdischarging the sulfid compound through the pipe 47 .and valve 48 to thehopper or pan 36.

receptacleand catches any surplusage of said compound whichmay bescraped from the bottom of the bolster 5 by the scraper or scrapers 51.seen in Figures 1 and 2. In case of any of the sulfid compound remainingon the bolster 5. after passing the scraper 51, the same is removed bythe water spray pipe 52 having the valve 53' and the ports 54 thereindischarging against the bottom of said bolster. as will be understoodfrom Figures 1 and 5, the water being caught in the trough 55. which mayhave a drain pipe, as 56. leading to any desired point. The bolster 5may be provided with an intermediate supporting roll 57. see Figure 2,and the sprocket chain 22 may be provided with a chain tightener 58, asseen in Figure 1. The agitator 31 for the sulfid compound is preferablymade in cylindrical sections 59, each section having the two helicalmembers cast thereon, as seen in Figure 3. said sections being keyed orfast on their supporting shaft, so as to rotate in unison therewith. butbeing readily disconnected therefrom according to requirements when thehopper or pan 36 is taken apart. It will be understood by those skilledin the art that the sulfid compound is a material'ofa thick plasticnature and the agitator 31 has an important func tion in keeping thecontents of the pan or hopper 36 at all times in a proper state ofagitation, so that the sulfid compound will be properly subjected to theaction of the feed roll 25 and applied with unvarying uniformity to thehide, skin or other article to be treated, and in case of any cloggingoccurring in the pan or hopper 36, the same is readily accessible uponthe removal of the bolts securing the ends 37 and the arms or brackets39 in position.

The operation is as follows The hides, skins or other articles to betreated are placed upon the conveyor or bolster 5 at the forward orfront end of the machine. as seen in Figure 1 and as they pass under thefeed roll and distribution means 32, the latter supplies to the surfaceof the skin a uniform coating of the sulfid compound, since the rapidlyrotating wiping strips 34 strike the surface of the feed roller in rapidsuccession, remove the sulfid. therefrom and throw it down on to thesurface of the hide, said compound being supplied to the flesh sidethereof, and permeating through it. The sulfid compound by reapound isthrown on the surface ofthe son of the employment of the agitatingdevices 31, is at all times kept at the desired consistency, so that itcan be applied with unvarying uniformity and the various moving partsare so timed that the sulfid comhide or skin in a substantiallycontinuous manner, so that the hide receives a uniform coating of saidcompound, and when the hides have travelled to the rear end of themachine as seen in Figure 2 they are removed therefrom by hand or anyother appropriate means.

The scraper or scrapers 51 which may be two in number remove any excessof the sulfid compound which falls into the trough 50 as will beunderstood from Figure 2 and in case of any of the sulfid compoundremaining on the bolster after passing the scraper, the same is removedby the water spray which is directed against the bottom of the bolsterthrough the medium of pipes 52. v

I desire to call special attention to the collocation of the agitator31, with respect to the feed roll 25 and the distributing means 32, thegeneral collocation and direction of rotation of these elements beingunderstood from Figure 6, wherefrom it will be seen that the sulfidcompound will be atall times properly agitated and directed towards thefeed roller so as to adhere to the surface thereof in the form of athin'sheet and will be properly removed therefrom and directed upon thehide, skin or other article to be treated, My invention is particularlyapplicable for applyin to any article, a mateterial of a thick, p lasticnature in an expeditious and mechanical manner and while I havedescribed my invention as being particularly applicable to hide treatingmachines, .it will be understood that it is equally useful in variousother applications and in I other arts.

It will now be apparent that I have devised a novel and useful sulphidemachine which embodies the features of advantage enumerated as desirablein the statement of the invention and the above description, and while Ihave, in the present instance, shown and described a preferredembodiment thereof which will give in practice satisfactory and reliableresults. it is to be understood that the same is susceptible ofmodification in various particulars. without departing from the. spiritor scope of the invention or sacrificing any of its advantages.
